My first open source project - a component for Angular 2+ to select categorized items.
Started as a hackday project at Zemanta. The main idea of this app is to encourage employees to contribute their part in the organization of birthday parties at a company.
An hour long talk at JSmeet (November 2016) focused on performance fundamentals every web-developer should know when building performant web-apps. Slides and lots of examples available at project's URL.
